The present invention is directed to an antigen found on the surface of rat and human pancreatic cancer cells and provides antibodies of high specificity and selectivity to this antigen as well as hybridomas secreting the subject antibodies. Methods for both the diagnosis and treatment of pancreatic cancer are also provided. This tissue marker of pancreatic adenocarcinoma, an approximately 43.5 kD surface membrane protein designated PaCa-Ag1, is completely unexpressed in normal pancreas but abundantly expressed in pancreatic carcinoma cells. Moreover, a soluble form of PaCa-Ag1 exists, having a molecular weight about 36 to about 38 kD, that is readily identified in sera and other body fluids of pancreatic cancer patients, using a subject antibody.

The invention relates to an intelligent lung cancer early cell pathological image recognition processing method, which comprises image pretreatment, image segmentation, laminate cell separation and reconstruction, cell character extraction and cell classification. The invention has the advantages that the image segmentation based on reinforcement learning uses incremental learning and continuous interaction with environment to search for optimized segmentation threshold value to obtain the segmentation effect which average value is 91%, the laminate cell separation and reconstruction uses B spline and modified deBoor-Cox method to simulate true cell edge better, the classifier uses general vote method to avoid low classifying accuracy of single classifier and improve total classifying accuracy, the application of two-stage classifier can reduce the possibility of false positive and false negative. Tests prove that the classifying accuracy of cancer or no cancer can average reach 93.8%, the classifying accuracy of squamous cell carcinoma, adenocarcinoma and small cell carcinoma average reaches 75%, and the false positive and negative average reach 4-6%.

The present invention relates to methods for improving the diagnosis of pancreatic and ampullary adenocarcinomas by making use of specific mi RNA biomarkers and/or mi RNA classifiers.

A two-tiered classification system that can be integrated with the current algorithm used by pathologists for identification of the site of origin for ‘malignancy with unknown primary ’ is presented. In use, morphology, immunohistochemical (IHC) studies, and microarry-based top tier gene expression classifiers first subclassify cytokeratin positive carcinomas into adenocarcinoma, squamous cell carcinoma, neuroendocrine carcinoma and urothelial carcinoma. Subsequently, organ-specific IHC-markers, if available, are used in conjunction with microarray-based second tier gene expression classifiers to assign the primary site of origin to the sample. This new hybrid approach combines IHC with a hierarchy of quantitative gene expression based classifiers into an algorithmic method that can assist pathologists to further refine and support their decision making process.

The invention discloses application of A-nor-5 alpha-androstane compounds in preparation of malignant tumor resistant medicaments. The compounds have the following general formula I, and comprise Ia, Ib, Ic, Id, Ie and If. The growth inhibition rate of the A-nor-5 alpha-androstane compounds for in-vitro human liver cancer cell Hep 3B, human breast cancer MDA-MB-231, human lung adenocarcinoma A549 and mouse melanoma B16 is higher than 85% on average, and even up to 99.98% to the maximum. The in-vivo test proves that the inhibition rate of the A-nor-5 alpha-androstane compounds for mouse tumors, such as intestinal cancer C26, liver cancer H22, Lewis lung cancer, breast cancer, B16 melanoma and the like, is higher than 50% on average, and even up to 63.19% to the maximum.
